Thanks for the report. A jumbo fix for one chip version may have
revealed an issue with another chip version. Could you please try
the following?
I checked the vendor driver r8168 and there's no special sequence

What would be interesting:
Do you set the (jumbo) MTU before bringing the device up?

That patch fixes the issue for me.

Great, thanks for the feedback!
